JOHN F. SHATSIOK AND ARTHUR O. SHATSIOK, OF ST. LOUIS, MISSOURI.

SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 400,496, dated April 2,1889. Application filed December 1'7, 1888. Serial No. 293,829- (Nomodeh) To" all whom it may concern:

Be it known that we, JOHN F. SHATSIOK and ARTHUR O. SHATSIOK, citizensof the United States, residing at the city of St. Louis, State ofMissouri, have invented a certain new and useful Improved Means ofOpening and Closing Window-Shutter Blinds, of which the followingis afull, clear, and exact description.

Our invention relates to means for operating that class of outsidewindow-shutter blinds which are opened and closed by bevel gearing andspindle from the inside of the window, and has for its object toautomatically lock or hold the shutter blind when in the open, closed,or intermediate position and to maintain the bevel-wheels in full gear.

Our invention consists in a bevel wheel or segment carried by theshutter-blind and engaged by a bevel-wheel fitted on and rotating with aspindle extending horizontally through the side of the window-frame; acollar carried by the spindle; a casing surrounding the col lar andspindle thereat and containing a spiral spring located around thespindle between the collar and outer end of the casing a bolt or catchhaving teeth and controlled by the spindle, so as to be thrown into orout of gear with a toothed spur wheel or segment carried by the bevelwheel or segment on the shutter-blind, and a knob or handle secured byan improveddevice to the end of the spindle within the building, thewhole operating so that on pulling the spindle by its knob or handle thetoothed bolt or catch is released from the spur-wheel on theshutterblind, when, by turning the handle ineither direction, thespindle is rotated, and bythe action of the bevel-gear the shutter-blindopened or closed radially on its hinges. On releasing the handle thespindle is returned by the spiral spring to its original position, andthrows the toothed bolt or catch into gear with the spur-wheel on theshutter-blind, so as to prevent any further rotation of the bevel-gear,and thereby lock the shutter-blind in any desired position.

Our invention also comprises means for preventing any vertical play ofthe shutterblind on its hinges when operated by the bevel-wheels, and somaintaining the latter in full gear at all times.

On the accompanying drawings, Figure 1 represents a side sectionalelevation of our invention applied to an outside shutter-blind Whenlocked in the open position, broken away; Fig. 2, a similar view thereofomitting part of the window-frame hinge-bracket with the shutter-blindunlocked ready for being closed; Fig. 3, a plan of the shutter-blind,broken away, and its combined parts, as seen to the right of Fig. 1;Fig. 4, a transverse section on line 1 1 in Fig. 1, looking to the lefthand and omitting the bevel-gear; Fig. 5, a transverse section on line 22 in Fig. 2; Fig. 6, a side sectional elevation showing a modificationof parts of our invention, as seen to the left of Fig. 1; Fig. 7, across-sectional elevation on line 3 3 in Fig. 2; and Fig. 8, asimilarview on line 4 at in Fig. 2, broken away, like letters of referencedenoting like parts in all the figures.

a represents a Window-shutter blind (broken away) provided With ordinaryupper hinges (not shown) and with a lower hinged bracket, 1), from whichprojects an upper arm, b, carrying in a planeat right angles to theblind or a bevel-toothed segment, 0, which is mounted axially on theupper end portion of the upright hinge d, projecting from the oppositehinge-bracket e, the latter being secured to the window-frame f in theusual manner. On the upper surface or back of the bevel-segment c is aweather hood or covering, g, having on its under side ahorizontallyarranged toothed spur wheel or segment, h, which isconcentric with the bevel-segment 0.

Within the window-frame f, adjacent and at right angles to thehinge-bracket e, is fixed a slotted box or casting, 0 in which ismounted the rear portion of a spindle, j, extending horizontally throughthe upright of the window-frame f, from the outside of the latter to theinterior of the building, where it termi- Dates in a knob or handle, k

The outer end of the spindle j, external to the casting i, is preferablysquare, and carries the vertically-arranged bevel-wheel Z, which engageswith the upper bevel-segment, 0, these parts being so arranged andfitted thatthe spindle j may be reciprocated' longitudinally whilerotating the bevel-wheel Z, which is at the same time maintained in gearwith the upper segment, 0, and prevented from moving endwise with oralong the spindle j by the outer face of the casting 2'.

Around the spindle j, at the inside of the window-frame f, is placed aloose ring or collar, in, (see also Fig. 5,) having inner projections,m, which look into corresponding notches or recesses, 11, formed atsuitable distances apart along the circumference of the spindle j,whereby the extent of the latter between the bevel-wheel land the insideof the window-frame f is adjusted to varying thicknesses of wall.

Inclosing the collar on and outlying portion of the spindle j is acasing, 0, which is secured to and projects from the in side of thewindowframe f. \Vit-hin the easiu g 0 is placed around the spindle j,between the collar on and the inner shoulder on the projecting end ofthe casing 0, a spiral spring, p, which normally presses the collar mtoward the windowframe f.

In the rear portion of the spindle j, inc'losed by the slotted box orcasting a, is a circumferential groove, g, which receives the lower endportion of a tooth or proj eetion, a", depending vertically from andsecured to a bolt, 8, which is mounted and capable of horizontalmovement in guides 1, formed on the insides of the casting '2', theouter end of the bolt 3 having vertically arranged teeth 2:, which, whenthe spindle j and collar on are in their normal positions, as beforenamed, engage with the teeth of the spur wheel or segment h on thewindow-shutter a, as seen in Figs. 1 and 3.

In operation, assuming the various parts to be in the relativeposit-ions seen in Fig. 1 that is to say, the spindle j in its extremeoutward position, with the bolt shaving its teeth a in gear with thetoothed spur wheel or segment h on the window-shutter a, which isthereby locked in the open position, on pulling the spindle j by itshandle it into the position seen in Fig. 2 the spiral spring p iscompressed by the collar m against the projecting end of the casing 0,at the same time the groove q, acting on the tooth or projection 0',constrains the bolt .9 along its guides ttoward the window-frame f, sothat its teeth u are withdrawn from the toothed spur-seg1nent h on thewindow shutter a, and the latter thereby unlocked, when, by partiallyrotating the spindle j to the left by its handle 7c, the bevel-wheel Zrotates the bevel-segment c, and so closes the shutter a radially on itshinges to any desired extent. On releasing the handle 7c the spiralspring 12 returns the spindle j to its original position, which throwsthe bolt 3 into gear with the spur-segment 7L, so as to prevent anyfurther rotation of the bevel-gear c I, and thereby lock the shutter ain the desired position. For opening the shutter a, the spindle is againpulled into the position seen in Fig. 2 and rotated by its handle to theright.

The great advantage of our invention is,

that the shutter-blind a may be automatically locked from the inside ofthe window in the closed or open or any intermediate position, so thatit cannot be moved from the outside.

Projecting from the top of the screw-plate of the hinge-bracket e, atright angles thereto along the adjacent face of the window-frame f, is acap or hood, r, Figs; 1, 3, and 4, which extends across the top of thebox or casting 17, for protecting the bolt .9 from ice and snow. On theouter edge of the cap 1) is a projecting lug or ear, t, which overlapsthe periphery of the weather-covering g on the bevel-segment c, forpreventing the rising of the shutter blind a on its wheel 01 during theoperation of the bevelwheel Z, which is thereby maintained in full gearwith the bevel-segment c, a gap, to, being form ed through the rim ofthe weather-covering g, for enabling the bevelsegment- 0 to be placed inposition on its hinge (I.

If desired, in lieu of the collar m having projections m, for looking onthe spindle, j, as in Figs. 1, 2, and 5, we may form or attach thecollar on (see Fig. 6) to the end of a tube, ac, which projects throughthe casing o, and constitutes the shank. of the handle 70, the spiralspring p being placed around the tube as, between the collar m andprojecting end of the casing 0, as in Fig. 1. Within the preferahlysquare interior of the tube :0 is inserted the corresponding end portionof the spindle j, having a series of holes,y, which are located atsuitable distances apart, so that when the spindle j is properlyadjustedto the locked position of the shutter-blind, with the collar min proximity to the windowframe f, the tube as may be fixed to thespindle j by a countersunk screw, 2, which enters one of the holes 1according to the varying thicknesses of the window-frame f.

For securing the handle 70 to the spindle j the latter is formed (seeFigs. 2, 7, and 8) with a T-shaped end, a, which is passed through acorresponding slotway, a", in the flange c, and when clear of the faceof the latter the T- shaped end a is partially rotated and drawnbackward, so as to engage in opposite recesses a formed in the face ofthe flange c at any suitable angle to the slotway (1 whereby the flangec is prevented from rotating on but constrained to rotate with thespindlej. From the T-shaped end a projects axially with the spindle j ascrew, (1', onto which the knob or handle is is screwed hard against theface of the flange c, and finally secured to the latter by screws 6,which are passed into the handle it through holes 6 in the flange 0. Bythis means the handle 70 is firmly secured to the spindle j and all playor working loose of the parts prevented.

1. In mechanism for opening and closing window-shutters, the combinationof a longitudinally-movable spindle mounted horizontally within thewindow-frame and provided with a handle, a bolt operated by saidspindle, and which is normally held in gear with a toothed spur Wheel orsegment on the shutter by a spiral spring located between a collar adjustably fixed to the spindle, a shoulder or fulcrum projecting from thewindow-frame, and abevel-wheel fixed on said spindle withthe bevel-wheelsegment carried by the shutter, substantially as described.

2. The combination of a bevel wheel or segment, 0, carried by hingedshutter-blind a, and engaged by bevel-wheel on spindle j, mounted inWindow-frame, and having adjustable ring or collar m', and spiral spring19, inclosed by easing 0, groove q in spindle j, bolt 8, havingprojection r and teeth u, and mounted between guides in window-frame,and spur wheel or segment h on bevel-segment 0, with knob or handle k,substantially as shown, and for the purpose described.
